EFFECT OF WEATHER PARAMETERS AND PARASITOID ON POPULATION BUILD UP OF STEM FLY MELANAGROMYZA SOJAE (ZEHNTNER) ON SOYBEAN AT JABALPUR
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 10
Abstract
In order to study the seasonal incidence of stem fly infestation in soybean crop, a trial was sown at the Experimental Field, Department of Entomology, Adhartal, JNKVV. Jabalpur (M.P.) during Kharif season 2014-15. The stem fly, Melanagromyza sojae (Zehntner) is considered as a major pest attacking the soybean crop. It was seen that the infestation of stem fly was first observed at 29th SW (third week of July). Thereafter, gradual increasing trend remain continued in subsequent weeks till 39th SW (fourth week of September). The parasitoid was observed from the vegetative stage till maturity of the crop.
